Application: konsole (2.7)
KDE Platform Version: 4.7.00 (4.7.0) "release 10"
Qt Version: 4.7.3
Operating System: Linux 2.6.37.6-0.7-desktop x86_64
Distribution: "openSUSE 11.4 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Searching a word in huge number of lines (few milions):
1. pressed Ctrl+Shift+F -> live search opened
2. entering each letter caused 10 second hang
3. after entering 6 letters and pressing "Next" (to find next occurence) application crashed

- Custom settings of the application:
scroll entries: unlimited

-- Backtrace:
Application: Konsole (kdeinit4), signal: Segmentation fault
